Help, vista not showing dual core

[ulater6000]

I recently upgraded my athlon 64 3500+ to an Athlon 64 X2 4200+

Under my computer properties, it lists my cpu as an athlon 64 x2 4200, but under task manager/performance it only shows one cpu graph

It should be showing two graphs... one for each core right?

I'm not too sure how vista works..it may be different and just reading the CPU differently but still utilizing 2 cores. You should run orthos to see if both cores are being utilized.

Crap, I found a dual core optimizer program from amd, and installed it. Now vista will not even load.

I ran CPUz, and it recogizes the x2, but it only shows 1 core(s) total? WTF?

Do I have a defective cpu?

Got it. Found out my BIOS was 8 versions old.

Did a flash update and is completely functional.
